Device for measuring the velocity of a fluid

摘要

To avoid disturbing measurement dephasings due to reflections from walls, the fluid velocity-measurement device comprises a pair of input-output transducers (18 and 20) located inside measurement chamber (16) which has the form of a revolution ellipsoid, each of transducers (18 and 20) being mounted at one of the focal points (F1 and F2) of the ellipsoid.
